US 2003/0198202 A1 · Selection of access point devices in a wireless communication network

Abstract

A wireless communication network contains a plurality of spatially distributed access point devices and station devices. Each station device communicating in the network exclusively via an associated one of the access point devices. The station devices select the associated one of the access point devices dynamically. Selection involves computing a respective measure of traffic load for each of the access point devices; identifying, for respective ones of access point devices, a set of co-channel access point devices that operate in a same frequency channel as the respective one of the access point devices; selecting the associated one of the access point devices dependent on a criterion based on the traffic load of the access point devices, so that, at least when part of the access point devices are equal on further criteria, if any, the associated one of access point devices is selected for which the co-channel access point devices have a least combined measure of traffic load of said part of the access point devices.
